Professional Applications & Engineering Value

This M10 shoulder screw delivers exceptional engineering value in precision assembly applications where accurate component positioning is critical. The alloy steel construction with black oxide finish provides excellent corrosion resistance while maintaining the 140,000 psi tensile strength required for high-stress applications. The 30mm shoulder length with precise diameter control serves as an ideal pivot point or bearing surface in machinery, automation equipment, and precision instruments. The low-profile socket head with knurled texture and 6mm hex drive ensures maximum torque transmission in confined spaces, reducing the risk of tool slippage and damage during installation. These metric shoulder bolts are engineered to solve alignment challenges while providing reliable, long-term performance in industrial settings.

Specification Summary & Compliance

This precision shoulder screw features M10x1.5 coarse thread with Class 5g6g thread fit tolerance, ensuring consistent fastening performance. The shoulder diameter maintains tight tolerance of -0.072 to -0.01 mm while the shoulder length tolerance is controlled within 0 to 0.25 mm for precise component alignment. Manufactured to metric system standards with right-hand thread direction, this fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict compliance standards.
